CASH REGISTER, INDICATOR, AND RECORDER.

SPECIFICATION forming part of Letters Patent No. 561,837, dated June 9,1896.

Application filed July 13, 1891. Serial No. 399,385. (No model.)

To (all whom, it may con/cern.'

3e it known that I, JOSEPH A. TREAT, a citizen of the United States,residing at Stuart, in the county of Guthrie and State of Iowa, haveinvented certain new and useful Improvements in a Combined Calculatorand Register, of which the following is a specification, reference beinghad therein to the accompanying` drawings.

This invention relates to newand useful improvements in a cash register,indicator, and recorder; and the invention consists in the peculiarconstruction of the following mechanism: first, in the construction ofthe registering` mechanism whereby with a single series of registeringwheels and a single group of keys a totalizin g-register is obtained;further, in the peculiar construction of the registering mechanismwhereby a sum may be added or subtracted; second, in the construct-ionof the recording or printing mechanism whereby each individual amount orsum is printed separately, and, further, whereby the additive orsubtractive character of each sum is likewise printed upon the record;third, in the peculiar construction of the indicating mechanism wherebya blank is normally exposed to view in all spaces of higher denominationthan the amount previouslyindicated; further, in the construction of ahood adapted to obscure the indication during the operation of the keysand a lever designed to be moved after the operation of the keysnecessary for the exhibition of any desired sum, to lift said rod, andto perform other functions; fourth, in the peculiar construction of theactuating mechanism for the various parts, fifth, in the peculiarconstruction of the actuating mechanism and locking device for thecashdrawe r; sixth, in the peculiar construction, combination, andarrangement of the various parts, all as more fully hereinafterdescribed.

In the drawings, Figure l is a side elevation of my improvedcash-register with the casin g removed, showing the parts in theposition with a key operated. Fig. 2 is a vertical cross-section thereofon line in yw in Fig. l, looking from the front. Fig. 3 is a rearelevation with the casing removed and the paper and paper-actuatingrolls removed. Fig. I is a horizontal section on line .r in

Fig. 6 is a similar elevation showing the register-wheelpartially operated. Fig. 7 is a similar elevation showing the positionof the parts when a sum is to be subtracted. Fig. 8 is a rear elevation,part-ly in section, of the registering mechanism. Fig. 9 is a rearelevation, partly in section, of the recording mechanism. Fig. l0 is avertical cross-'section on line y y in Fig. l. Fig. ll is a detachedperspective view of the lifting plate and the mechanism for shifting it.Fig. 12 is a front elevation thereof. Fig. l'l is a horizontal sectionon line fc fr in Fig. l. Fig. let is a detached elevation of a lock forthe resetting-lever. Fig. 15 is a plan view of a portion of theprinting-strip.

A is the casing of the machine, of suitable shape to receive theoperating parts.

B is a series of key-levers journaled upon the transverse shaft C andprovided at their forward ends with suitable finger-pieces. Theiinger-piece of each lever is marked with its value, and l use ten keys,one for each digit and a cipher-key D. These levers are so arranged asto impart a movement proportionate to its value to the actuatingmechanism for the register and indicator and recorder. This I preferablyaccomplish by journaling them upon a common fulcrum and making thelever-arms of different lengths; but this may be accomplished by othermeans, such as arranging the fulcrums diagonally across the machine orby giving them a different length of movement before striking theoperating mechanism, or any other suitable means.

E is a plate journaled upon the shaft lf near the front of the machine.This plate is adapted to have a sliding movement upon its fulcrum. Theplate is of sufficient width to extend across all of the keys and islifted by every key whenever it is operated. At its rear end this plateis provided with the iingers a., c', a2, and as, Fig.' i, one for eachmonetary denomination which it is designed to indicate, register, orrecord.

b, b', b2, and Z13 are a series of vertically-actuating rods placed inthe rear of the machine. These rods are of successive higherdenomination and are designed to be succes- IOO sively operated by theiingers on the plate E. To accomplish this, I arrange a device forlaterally shifting the plate E after the depression of each key untilthe desired sum has been registered, when a resetting-lever returns theplate to its normal position.

The construction which I preferably employ for laterally shifting thisplate consists of the downwardly-extending arm c, formed at the rear endof the plate E. This arm is provided at its lower end with a spring-pawlThe arm c is also provided with a finger d' at the front side thereof,extending down to substantially the same distance as the pawl d, Figs.Il, l2, and 13.

c is a stationary rack arranged transversely the machine, and e is ashifting rack arranged beside the stationary rack and actuated by aspring fl This shifting rack has a limited sliding movementcorresponding` to the length of the slot f. These parts are plainlyshown in Figs. Il, l2, and I3.

Upon the shaft E is a shifting-spring F, which bears at one end againstthe stationary lug F and at the other end against the lifting-plate.This spring is under tension in the normal position of the parts andacts to move the lifting plate toward the left of the machine. Itstension is suiiicient to overcome the tension of the spring f. In thenormal position of the parts, the lifting plate being in its lowestposition, the pawl d is in engagement with the shifting rack e. Thetension of the spring f moves that rack toits farthest position to theleft, in which position the pawl (l is in line with the interdentalspace inthe rack e. The depression of a key raises the lifting plate androcks the arm e forward, moving the pawl and the finger d into thestationary rack. As soon as the rack e is released it moves to the limitof its movement to the right by the expansion of the spring f. Upon thereturn of the arm c it engages with the second space in the rack el. Thespring F, overcoming the tension of the spring f, moves into line withthe second space in the stationary rack, carrying the lifting plate acorresponding distance to the left- This operation may be repeated asufficient number of times to carry the lifting plate to the end of itslateral movement. To return it to its initial position, I employ abell-crank lever g, having one arm in engagement with the lifting plateand the other beneath a lever II, which I calla resetting-lever, as itsfunction is to reset the plate and put other parts in position to beoperated by the next operation of a key. The depression of this levermoves the lifting plate to the right, compressing the spring F, the pawld allowing the arm c to move to the right over the teeth in the rack c.The function of the finger d is to form arigid connection between theshifting plate and the stationary rack, so that during the operation ofa key it will be engaged with the racks and prevent the operation of theresetting-lever to shift the lifting plate. In the normal position ofthe parts this finger extends beyond the racks, as plainly shown in Fig.Il.

When the lifting plate is in its initial position, the depression of akey will lift the actuating-rod l), the depression of a second key willlift the actuating-rod h, and the succeeding operations will lift therods h2 b3 successively.

It will be observed that the lifting plate is provided with fingerscorresponding to the number of actuating-rods.

In the initial position the units-finger d on the plate engages beneaththe units-rod b, and the operation of any key operates that rod. As soonas the key is released the plate is shifted, the units-finger CL isdisengaged, and the tens-finger a engages beneath the tens-rod b. Thedepression of a key now actuates the tens-rod. As Jthe shifting followseach successive depression of a key, the units, tens, dollars, andtens-of-dollars iingers on the plate will successively operate theactuating-rod of corresponding denomination. The plate is returned toits normal position by the resetting-lever II.

Each actuating-rod is alike and is correspondingly moved by theoperation of any key when the plate is engaged therewith. Each rodactuates the registering mechanism and sets the recording mechanism andindicating devices. The resetting-lever actuatos the printing mechanismand elevates the hood to expose the indication and sets the trippingmechanism in position, so that the succeeding operation of a key willhide the indication and return the parts to their initial position.

Each actuating-bar is provided on its rear face with the racks g 7L,Figs. l and 3, the former actuating the type-wheels and the latter theindicating-wheels.

0I are the drive-pinions for the type-wheels j, j ournaled upon theshaft j, Fig. i), and arranged in close proximity to each other. This Iaccomplish by means of sleeve 7s, connecting the drive-pinion andtype-wheel of the highest and lowest denomination.

Each type-wheel is turned by the raising of its actuating-rod. A numbercorresponding to the value of the key struck is brought in the path ofthe printing-hammcr, and is held in its adjusted position by aspring-pawl fr" engaging with the rack 2 on the actuatingrod, Fig. 9.Each type-wheel has upon its face figures corresponding with thekeysthat is, a cipher and ten digits-and between the O and 9 is a blankspace lt', a fractional part of the circumference, Fig.' 0.

t is an inking-ribbon, Fig. 2, extending across the face of thetype-wheels, carried by suitable spools. These spools maybe turned bythe operating mechanism or by hand, as desired.

l is a paper strip, Fig. l, wound around the spools m m and passing overidler-rolls m2, which bring it in proper relation to the typewheels.

n is a hammer extending across the face of all the type-wheels. Thishammer is actuated by the resetting-lever H, which strikes the arm nthereof, Fig. l, in its upward movement. The resetting-lever alsocarries the pawl o, which engages a ratchet-wheel on the spool m5. Asthe actuating-arm of the lever is raised the pawl moves over the teethof the wheel. As it is returned by the spring o' the spool is revolvedand the paper moved in proper position for the next record, Fig. l.

p is a numbering-wheel, Fig. 9, having iigures thereon from l, to 10,these figures being printed beside each sale, thus arranging them ingroups of ten-an assistance in counting the number of sales. This wheelI preferably arrange between the tens and dollars wheels and arrange thetype in a small circle, which forms the period or decimal point, andwhich takes up no extra room on the paper. This wheel is turned a tenthof a revolution after the actuation of the keys to record any desiredamount by means of the pawl q engaging with the wheel and actuated bythe setting-lever II by means of the connecting-rod q. The imprint fromthis wheel is shown in Fig. l5.

As I use this recording mechanism in connection with a registeringmechanism with which I may add or subtract to indicate whether a sum isadded or subtracted, I use a printing-plate r, Figs. l and 9, having aplus and minus sign thereon. This plate is connected by means of a rod rwith the shifting mechanism of the register, so arranged that when theregister is in position for adding the plus sign is printed, and when itis in position for subtracting the minus sign is printed opposite eachsum recorded.

If desired, the plus sign may be omitted and the minus sign alone maybebrought into position to indicate subtraction, the absence of a signindicating addition.

To record a sum such as $4.09, the operator iirst strikes the 9 key,which moves the units-wheel to 9; nextthe 0 key, which moves thetens-wheel to 0 g next the a key, which moves the dollars-wheel to 4.The operation of the resetting key-lever prints this sum upon the paper,with the plus sign if it is added and the minus sign if it issubtracted, and the numbering-wheel prints the proper number, as shownin Fig. l5. As each actuating-rod rises it turns the indicating-wheels s(see Fig. l) by its engagement with the pinions s thereon and brings theproper number opposite the aperture S2 in the casing. Theindicating-wheels have marked thereon iigures from l to 9, a cipher, anda blank space s2. The cipher is exposed by the operation of thecipher-key. Thus I obtain an exact indication without exposing cipherson indicating-wheels which may not be required in such sums as $4.09. Ifthe cipher instead of the blank were normally exposed, the indicationwould be for $04.09, which I deem undesirable.

The registering mechanism is actuated by the bars b h b2 b3 through themedium of the key-levers and lifting plate, and it is of the followingconstruction. (Shown in Figs. l, 2, 3, 5, 6, 7, and S.)

I are frames apertured to slidingly engage with the actuating-bars?) b',tbc. This frame is provided with a link-shaped yoke on its front side,having racks I' I2 upon the inner faces of the vertical portionsthereof. These racks are separated suiiiciently to enable theregister-actuating pinions J to lie freely between and engage witheither rack. These pinions J and the register-wheels K, which they areadapted to actuate, are all journaled upon a common shaft K', which issecured at the top of the swinging frame K2, journaled at the lower endin suitable bearings in the casing.

L is a spring acting on the lever L to hold the frame in position toengage the pinions with the rack I. L2 is a cam-wheel against which thislever bears, and L3 is a shaft on which this cam is secured. By turningthe crank M at the end of the shaft, Figs. 2 and 3, the bearing M on thecam rocks the lever, throwing' the 'pinion into engagement with the rackI2.

N is a shoulder on each rod Z) U, rbc., normally in position a shortdistance below the lower edge of the frame and adapted to strike it andraise the frame, with the rod, to actuate the register-pinions. The lostmotion between the rod and frame is sufficient to allow the rod to beactuated by the cipher-key without actuating the frame. The frame restsupon a stop N2 in its initial position. Upon the actuation of adigit-key the rod is carried up a distance proportionate to the value ofthe key, and the rods are successively operated by the lifting plate, aspreviously described.

To transmit the motion from the pinions to the register-wheels and fromone wheel to another, I employ the following mechanism:

Each pinion J has a short sleeve O extending from its inner face, whilethe registerwheel is recessed by forming a ilange O' on its periphery. Pis a disk secured to the end of the sleeve O and arranged within therecess of the register-wheel. Between the pinion and the disk is areversible spring-pawl P', pivoted to the disk at the edge, having thearms P2 P3 on opposite sides of its stem Q. This stem is suitably shapedto pass the shaft K and extends to near the bottom of the disk, where itengages with a spring-pawl Q', having inclined bearings R R.

S are lugs on the inner face of the iiange O corresponding to thenumbers on the periphery. S are stationary lugs on the inner face of theyoke on opposite sides of the stem Q and in the path of the lug S2 onthe stem. The lugs S act as a fulcrum to shift the arm P or P2 intoengagement with the lugs S when the frame K2 is moved by the cam L2.

The raising of the frame when the pinion ITO is in engagement with therack I', Fig. 5, will cause the pinion to turn toward the front of themachine. The arm P3, being in engagement, will cause the register-wheelto move with it and add the sum to the number already expressed. Inreturning the springpawl T will hold the register-wheel in its adj ustedposition, the stem Q sliding up the incline R as the arm P3 passes thelug S.

Vhen the pinion is in engagement with the rack I3, it will rotate in theopposite direction as the frame is raised, and the arm P3, being inengagement with the lugs S, will carry the register-wheels in theopposite direction, subtracting the sum from that already expressed.

T is a pinion, with which a gear T2 on the periphery of the tensregister-wheel engages.

T3 is a tooth or segmental gear on the unitswheel, adapted to mesh withthis pinion once in cach revolution and move the tens-wheel a fractionaldivision to carry one.7 Corresponding pinions T carry from the tens todollars and from dollars to tens of dollars, duc., and I thus obtain atotalization.

U, Fig. 5, is a lug on the actuating-bar, to positively bring the framedown with the rod, a spring s4 in the indicating-wheels acting with itstension to return the rods when released by the pawls t. These pawls t"are journaled upon a stationary bar U3, Fig. 9, and pass beside amovable or tripping bar U3, which has cross-bars or pins U* in front ofeach pawl. Each pawl has a spring acting to hold it in engagement withthe ratchet on the side of the actuating-bars b h', ttc., while the barU3 has a spring U5, Fig. 9, acting to force the cross-bar back, carryingthe pins U4 normally out of engagement with the pawls. The mechanism foroperating this trippingbar and throwing down the previously-operatedrods, returning the parts to a position for another-registration, is asfollows:

V, Fig. l0, are legs pivoted to the sides of the key-levers near thefront and extending some distance below, engaging in guide-bearings V inthe bottom casing of the machine above the cash-drawer V3. They alsopass through apertures in a horizontal reciprocating bar V3, and areadapted to move that bar in their downward movement by means of the lugsV 4, formed on the side of these legs. This bar at its end bears againstthe lever V5, Figs. and l0, which extends rearwardly and upwardly to apoint opposite the end of the tripping-bar U3. (See Fig. 9.)

VU is a hood-bar carrying a blind or hood V7, which is adapted to coverthe indication in its lower position. This rod is held in its elevatedposition, Fig. 2, by means of a springpawl V8 (similar to the pawls 17)engaging a detent or shoulder on the rod. Pivoted to this rod is theswinging tripper V9, lying between the lever V5 and the tripping-bar U3.The pivot of this tripper engages in a slot in the rod, as shown in Fig.9. Vhen the pawl Vsholds the rod up, the tripper is suspended by itspivot in the lower end of the slot.

The operation of a key moves the lever Vs laterally, carrying thetripper into engagement with the tripping-bar, which it moves into theposition shown in Fig. 9, disengaging the pawls t" from theactuating-bars and the pawl V3 from the rod V, which drops the length ofthe slot, carrying the shoulder below a point where it is impossible forthe pawl V8 to rengage until the rod is again lifted. The parts are heldin this position during the time the lug V4 is in engagement with thebar V3, Fig. l0. As the key approaches its limit of movement the reducedportion W on the leg V enters the bar and allows the spring IV of thelever V5 to return the lever, disengaging the tripper and allowing therod and tripper to fall below the bar V3. It remains in this positionuntil the resetting-lever is operated, which raises the hood-bar,displays the indicating-wheels, and is held elevated by the pawl V8until another keyis operated. Thus the hood obscures the indicationuntil it is completed, and then when the resetting-lever is operated thehood is raised and the indication Vis exposed until another key isstruck, which throws down all previously-operated rods and the hood.

IV3 is a partition near the front of the cashdrawer, into which the legsV enter in their downward movement, as shown in Fig. l, preventing themovement of the cash-drawer during the depression of a key.

As the cash-drawer is actuated by the rcsetting-lever, it is evident ifthe cash-drawer is locked that the resetting-lever cannot be actuated,and therefore this engagement of the leg V into the drawer also locksthe resetting-lever during the depression of the key.

In order to insure the complete depression of the key after it hasstarted, I arrange a spring-pawl IV3 upon each key, which engages with asegmental rack IW on the front of the casing.

The mechanism which I employ for throwing out the drawer is shown inFig. l. It consists of a curved lever X, pivoted in the rear of thecasing and actuated by the upward movement of the resetting-lever II, towhich it is connected by means ot' the connectinglink X. The upwardmovement of the end of the resetting-lever moves the lever X laterallyand pushes out the drawer.

The resetting-lever is also provided with a lug X3, which engages infront of the rear edge of the drawer and holds it locked until the leveris elevated. I also provide means for locking the resetting-lever aftereach opera-tion thereof, which mechanism I have shown in Fig. lat andwhich consists of the locking-plate Y, pivoted above the normal positionof the resetting-lever and weighted to swing over said lever, as shownin dotted lines in Fig. l-i. This plate is provided with an arm Y', withwhich a hook V3, secured to the IOO IIO

lifting plate, is adapted to engage at each uprocks the plate Y ont ofengagement with the resetting-lever, in which position it is held bymeans of the spring-catch YS engaging with the pin Y'L upon the plate Y.Then the resetting-lever is again actuated, it lifts the latch Y2 anddisengages it from the plate, allowing the plate to assume its normalposition. As the lever descends it moves the plate back sufficiently toallow it to reach its initial position, when the plate swings over itand locks it, as before described. Thus the resetting-lever is lockedbetween its successive operations until the key has been struck.

I preferably provide means for preventing the retrograde movement of thesetting-lever, and this may consist of the device shown in Fig. la,where I have shown a gravity-pawl Z, pivoted to the rear end of theresettinglever and adapted to engage with the rack Z' upon a part of theframe in rear of the said resetting-lever. As soon as the resettingleverhas started on its movement, this pawl, engaging with the rack, willprevent its retrograde movement until it has completed its stroke, whenit may be inclined upwardly to allow the lever to ret-urn toits normalposition.

The pawl Z is prevented from inclining upward by the proximity of therack Z and bar II. As it reaches the top of the rack it is free to moveup and thereby allow the bar II to fall.

The operation is as follows: Then the amount $4.09 is to be registered,recorded, andindicated, the operator first presses down the key bearingthe number 9 thereon, which elevates the plate E to the extent of themovement of the long arm of the key-lever. The movement of the plateforces up the rod l), which is normally located above the unitsfinger aof the plate. The upward movement of rod b rotates the firstprinting-wheel j by the rack g engaging the gear on the wheel, and atthe same time rotates the indicatingwheel s, the extent of the movementof the rod being suiiicient to expose the figure 9 on both the unitsprinting` and indicating wheels, the former to the opening and thelatter to the hammer. This upward movement of the rod carries theshoulder N thereon into engagement with the first of the series of yokesI, lifting the same from the rest N2 and carrying it upward a distancesufficient to register the added amount 9 on the unitsregister wheel ofthe series, the handle M having previously been turned to throw the camL2 out of engagement with the frame L, allowing the spring L to forcethe pinions J into engagement with the adding-racks I of the yokes, andat the same time the rear lng S engages the lug S2 on the arm Q, rockingthe same toward the front and causing the engagement of its lower endinto the outer notch of the pawl Q', thereby carrying and holding thearm I2into the path of or engagement with one of the lugs S on theiiange of the units-register wheel, causing a lock in the direction ofthe adding movement of the pinion .I and the register-wheel. Vhen theframe carrying the register-wheels is moved by the spring into theadding position, the cord r is drawn forward, lifting or drawing theplate yr up and alinin g the plus sign thereon with the platen orhammer. rlhe rod Y: havin g been elevated, it is held in its elevatedposition by the pawl which, as stated, is held normally in engagementwith the teeth 2 thereon by the individual pressure-springs. Before thekey J has been pressed down the dog d on the arm c of the plate E isheld in the last notch of the sliding rack e, the latter being' forcedback to its extreme limit. As the plate E is raised the dog d is movedforward into the groove of the stationary rack c, and as the plate Efalls when pressure is taken from the key the dog enters the secondgroove in the sliding plate (the latter having been moved forward by thespringfl when the dog was in the stationary rack) and the spring F onthe plate forces the movable rack back so that the notch in which thedog rests will be opposite the second groove in the fixed rack, thusallowing the spring F to carry the plate E one notch toward the left ofthe machine, and thereby carrying 'linger a beneath the rod ZJ'. Yhilein this position the operator presses down the cipherkey, raising theplate E a limited distance, (owing to the length of the lever-arm,)which raises the rod b' and actuates the printing and indicating wheelsto present the cipher sign to the platen or hammer and the cipher on thetensindicating wheel to the opening in the casing. The limited. play ofthe rod between the yoke I and shoulder N prevents the cipher-key fromactuating the tens-yoke. The rod b is held in its elevated position byits pawl z', and the plate E is moved one notch farther toward the left,carrying the finger a2 below the rod b2. The key bearing the figure etis now pressed down, and in a manner similar to that of the first keyactuates and sets the dollar printing and indicating wheels and actuatesthe dollar-recording wheel. lVhile the rods l), b', and b2 are in theirelevated position, the indicating-wheels set to expose the figures eLOQand the printing-wheels set to present the fi gures 400 to the hammer,the resetting-lever Il is pressed down, (the keys having assumedtheirnormal positiom) turning the lever X on its fulcrum, therebyforcing open the drawer, the lug X2 moving out of engagement with therear of the drawer as the resetting lever is moved up. The upwardmovement of the resetting-lever forces up the rod turning thenumbering-wheel one point and presenting the proper number to thehammer. The further movement of the resettinglever strikes thehammer-arm n and forces the hammer against the paper strip, making theimprint of the figures thereon. The down movement of the forward end ofthe resettinglever carries the same into engagement with the horizontalarm of the bell-cannk g, as shown in Fig. 11, forces the vertical armIIO thereof in against the plate E, and moves this plate back toitsinitial position, the dog d on the end of the arm e passing over theribs on the bar e and iinally coming to rest in the iirst notch thereof,directly opposite the iirst notch of the stationary rack e, in properposition for subsequent operation of the keys. The upward movement ofthe long arm of the resetting-lever forces up the bar VG, which raisesthe hood V7 and exposes the numbers on the indicating-wheels. As the barVj is raised the pawl V s engages in the notch therein and holds the barin its elevated position and the tripper V9 directly opposite the end ofthe sliding bar U3 and the lever V5. When the long arm of theresetting-lever falls, it rotates the friction-wheel M3 of thepaper-carrier one notch, thereby carrying the printed matter below thetype. The parts being in the position above indicated, the downwardmovement of a key in making the next entry forces the slide V3 towardthe left against lever V5, throwing the inner end of this lever againstthe tripper V9 and moving the sliding bar U3 to the right and the pinsU4 into engagement with the pawls t' and Us, releasing the hoodbar andthe bars b b Wand allowing the same to fall. Vhen the amount is to besubtracted, the register-wheel frame is tilted by the cam L until thepinions J engage the racks I2. The operation of the several parts is thesame as during the addition, with the exception of the reversing of theswinging pawl Q of the register-wheels and the replacement of the pluscharacter by the minus character, which movement is caused by theslackening of the cord r'.
